Unlimited multiplexing testing system for press type switch

An unlimited multiplexing testing system for press type switch, comprising:

• a board, being provided a plurality of electrical connection units thereon;
• a plurality of fixing bases, being disposed on the board;
• wherein a plurality of objects that are pending to be tested are respectively disposed in the plurality of fixing bases, thereby making the plurality of objects be electrically connected with the plurality of electrical connection units, respectively;
• a test controlling module, being disposed on the board, and having a first communication unit;
• a first interface unit, being coupled between the test controlling module and the plurality of electrical connection units thereon;
• a button punching module, being located over the plurality of fixing bases, and being controlled by the test controlling module;
• and
• a host device having a test mode decision unit and a second communication unit;
• wherein each of the plurality of objects has a key-press portion, and the test mode decision unit being configured for deciding a specific test mode according to a type of the object;
• wherein the host device transmits a signal of the specific test mode to the test controlling module via the second communication unit and the first communication unit, such that the button punching module is controlled by the test controlling module so as to apply at least one button punching test procedure to the plurality of objects based on the specific test mode.
